A couple years ago when I was in California teaching workshops, I got a chance to visit the Sequoia National Park and was amazed at the size of these trees. They grow close to the top of a mountain which is a crazy twisting, turning, slow16 mile long road to get up to the top. If you get motion sickness take Dramamine before you drive up. I first hiked to see the largest of the Sequoia’s called General Sherman. Very impressive but I couldn’t get near it to take a picture of me standing next to it so you can see the enormous size, plus the sun was blasting on the trunk making it useless to shoot. I did find one large tree that was right next to the trail that I could pose by to give you some scale of these trees.
Here is a shot of a hiker in red pants, black top on the right side of the tree, look how tiny he is.
Not much in the way of macro here to shoot, as the understory is just dirt covered in needles, and leaves and very little plant life anywhere. Here are some images of the tree.
